function on TMA slides! The layout of
TMA slides may mislead the detecting algorithm.
Fill holes inside scanmap
:
If selected, the holes inside the specimen will also be scanned.
Often these holes contain small sample objects that otherwise would not be scanned.
Remove specks
:
If selected, the scanner does not digitize objects smaller than the
predetermined size. This helps filtering specks and other uninteresting objects out.
Set the maximum volume of specks manually in the setting window
.
Threshold settings
have two different statuses:
•
Auto threshold
: It automatically detects the specimen in the preview image.
Caution!
Make sure that the detection result is acceptable for you. Otherwise
set the threshold value manually.
•
Manual threshold
– Set threshold value manually, or calculate value on the actual
preview with
Calculate Threshold
function which is active only if setting the value
manually. This sets the sensitivity of the specimen detection. To set the desired threshold
value manually, change the setting in the
Specimen threshold level
selection box in the range
of 0-255. The default value is 212. Smaller values result in a more sensitive scanning, meaning
that more areas will be digitized, however, this may also include specks or other
imperfections of the slide. Greater values result in a less sensitive scanning, but it is possible
that some of the smaller specimen areas will not be digitized.
